Mitochondrial DNA College Essays Samples For Students

Question 1

The type of bloodstain evidence at the scene is a cast off pattern. According to Becker (2005), a cast-off pattern normally results in blood striking nearby surfaces such as walls, floors and ceilings. A cast-off pattern indicates that a blunt force trauma to the head. The large wound on top of the head is indicative of repeated use of the blunt force weapon on the victim.
The first step in the documentation process of the room would involve conducting an initial scan of the room to ascertain the evidence present. This would then be followed by photographing of the scene in ...

Genes are contained in an organelle referred to as mitochondria. This organelle is responsible for providing the body with the energy needed to run all the cellular activities. Mitochondria contain their own genome that is specific to a particular organism. This is essentially distinct from the nuclear genome that is obtained from both the father and mother and is harbored in the nucleus; as the mitochondrion genes are inherited exclusively from the mother. mtDNA occur in numerous numbers in the cell owing to their small size and they do not undergo recombination. They are the genetic markers that have been ...

Abstract:

DNA (Deoxyribonucleic acid) is hereditary material found in most organisms and carries the genetic information required to build and maintain a living organism. DNA was first discovered in the late 1800's, but it was not until scientists unraveled its structure in the 1950s that its importance in genetics and the whole field of biological sciences became realized. This paper assesses the structure, history and applications of DNA into solving real world problems in medicine, agriculture, biochemical research and forensics. DNA can replicate itself which ensures that genetic information and consequently biological traits can be passed on from one generation to ...

Sometimes Forensic Casework items consist of less than 100 picograms (pg) of template DNA which, if we assume 3.5 pg of DNA per haploid cell, can be equated to approximately thirty haploid cells or fifteen diploid cells are termed as LCN DNA (low template DNA or LT DNA). (Gill 17)
Such low copy number (LCN) samples exist due to several factors like damaged or degraded DNA, oligozoospermia or aspermic perpetrators or extended interval post coital samples, where there is loss of sperm over time because of the effects of drainage or host cell metabolism. From crime scenes, Trace ...
